Abstract: 924,125. Covers for resisting fluid pressure. PARKER-HANNIFIN CORPORATION. May 21, 1959 [May 22, 1958], No. 17236/59. Class 123 (1). [Also in Group XXV] A removable safety closure for preventing the escape of liquid which may leak past a spring-closed check valve 20 closing the filling and draining opening 8 in the bottom plate 5, e.g. of a fuel tank of an aircraft with an underneath refuelling system comprises a closure plate 28 having a mounting ring 29 with bayonet lugs 34 engageable over bayonet lugs 25 on a skirt 14 depending from a valve-bearing spider 12 which is supported within a valve housing 6 bolted over the opening 8. A fuel leakage chamber 58, floatingly mounted on the closure plate 28, supports, on an upper interned flange 60 of its cylindrical wall 59, a sealing ring 62 for engaging with the under face of a seat flange 16 directed inwardly from the skirt 14. A rigid reinforced backing plate 68, with its edge 70 co-operating with an outwardlydirected flange 64 which clamps a flexible diaphragm 65 to the lower end of the cylindrical wall 59 and is located beneath the lugs 34, and a flat spring 71 are interposed between the chamber 58 and the face plate 28. A yieldable sealing ring 17, clamped between the edge of the valve body 20 and a securing ring 21 secured thereto, is urged, by a spring 19, upon the upper face of the flange 16. The closure plate 28 is cut-away at 39 to provide a half-circular handle 40 having bearings 41 swingably mounted on a pair of trunnions 38 projecting radially outwardly from the mounting ring 29 which also carries a plate 43 with an up-turned projection 45 disposed to be received in a corresponding slot 26 formed in a thickened portion of the valve housing 6. A cam member 46, fixed to the plate 43, is releasably engageable by the cross-pin 57 of a locking-pin 54 mounted in a cup 52 which is fixed, by a clutch ring 53, in an opening in the handle 40, a spring 56 in the cap 52 urging the head 55 of the pin 54 out of the cup 52. The handle 40, releasable by turning the pin-head 55, can be turned to release the bayonet connections 25, 34 and free the closure plate 28 so that a refuelling or fuel-discharge nozzle can be mounted in the opening 8 in the wellknown manner for displacing the valve 20 upwardly. Upon re-application of the closure plate 28 the projection 45 is first located in the slot 26 and then the plate 28 is pressed upwardly and rotated until the bayonet lugs 34, 25 engage and one lug 25 lockingly engages behind a detent pin 36 on one of the lugs 34. Only in this position can the handle 40 be swung up so that the locking pin 54 can be engaged with the cam member 46 with its end received in a recess 27 in the valve housing 6. If leakage occurs past the valve 20 liquid pressure in the chamber 58 urges the sealing ring 62 into tighter engagement with the flange 16. Specification 790,894 is referred to.

Title: Apparatus for tying stacks of bags, cardboard sheets or other flat objects
Inventor: BERGHGRACHT MARIUS
IPC: B65B27/08
Filed: 1968-04-10
Abstract: 1,211,458. Binding machine control. M. BERGHGRACHT. 10 April, 1968 [18 April, 1967], No. 17408/68. Heading B8C. In a machine for binding piles of flat objects either once or twice, moving piles of the objects actuate means to arrest piles at the binding station and start the binding operation, and actuate means to stop a delivery conveyer. Further means actuated by the tying mechanism, which includes a compressor, starts the conveyers, and a selector switch determines whether one or two binding operations are performed. Piles 25, 26 of flat objects e.g. bags, cardboard sheets &c. are moved by a belt or other conveyer 1 on to belt or other conveyers 6, 7 at the binding station, where, for a single binding operation, they contact a switch 24 adjustable longitudinally of the conveyer which stops the conveyer 1, to form a gap between adjacent piles. Another adjustable switch 23 is then contacted, this stops conveyers 6, 7 and actuates the binding mechanism (not detailed) including a compressor. After binding, a movement of the compressor actuates a further switch (not shown) to re-start conveyers 1, 6, 7, to discharge the bundle on conveyer 22. For two bindings another switch, which may be identical with 23, is changed from a single tying operation position to a double tying one by the selector through a multiple switch. Switch 24 is now made inoperative and the new switch 23, when contacted by the pile, stops conveyers 1, 6, 7, and starts the binding operation, after which a switch is contacted by the compressor to re-start conveyers 6, 7. The bundle is then moved until it releases a switch 27, which only operates when a pile is depressing the switch 23, and causes the conveyers 6, 7 to stop and the binding means to operate for a second time. A switch is then actuated by the binding means to start conveyers 1, 6, 7. In another embodiment, the piles are stopped by raising bars (20), Fig. 4 (not shown), between the belts (17) of conveyers 6, 7, to lift the piles from the conveyers.

Abstract: 1,177,954. Deflecting propulsive jets. ROLLSROYCE Ltd. 20 April, 1967 [21 April, 1966], No. 17439/66. Heading B7G. [Also in Division F1] The invention relates to a variable area jet propulsion nozzle (see Division Fl) and is described with reference to a nozzle which may be rotated about an axis so as to control the direction of discharge of the air or gases therefrom. The pilot's control lever for selecting the nozzle area is connected to a demand input shaft 85, the shaft 85 being connected to an epicyclic gear unit 80 the ring gear of which is also in engagement with the gear segment 87 which is supported on the nozzle 16 for movement relative thereto about the axis of the nozzle bearing 20. The gear segment 87 also meshes with a gear 88 secured to the shaft 61 of the control unit 60 for the nozzle area so that rotation of the shaft 85 is transmitted to the shaft 61. The planet carrier 82 of the epicyclic gear unit 80 is connected through gear 89 to a gear segment 90 secured to the nozzle 16 concentric with the bearing 20 so that rotation of the nozzle does not affect the demand setting of the shaft 61. When the nozzle is rotated the segment 87 must travel together with the nozzle to prevent unwanted rotation of the gear 88 and shaft 61. The segment 90 and gear 89 ensure that when the nozzle rotates, rotation is imparted to the annulus 84 independently of the input shaft 85 and the segment 87 is moved together with the nozzle.

Abstract: 530,529. Tobacco. TJEBBES, K. June 15, 1939, No. 17483. [Class 130] [Also in Group XIII] In a process for the drying and fermentation of tobacco leaf or cut tobacco, circulating air is passed through a cooling plant arranged externally of a tobaccocontaining chamber so that the air is cooled and condensed moisture is removed, and is then passed directly and without further treatment into and through the tobacco chamber so as to dry the tobacco while maintaining it at the desired temperature. In the form shown, the tobacco is hung on yarns 1 between poles 2 in a chamber 3 housed within a shell 5 forming an air jacket and having sliding air-inlet shutters 6 and casement windows 7 for the outlet of air. Cooled air of the required temperature and humidity is supplied by a cooling plant in an adjoining chamber 4 to inlets 8 under the roof of the chamber 3 and escapes through outlets 9 below a perforated or gridded floor. The cooling plant, Fig. 2, comprises air-cooled condensers 12, 13 in series, with controllable air inlets 15 on the condenser 12 and a pressure fan 14 between the condensers, the air being cooled by a medium circulated through coiled pipes 21, 22. The air may be exhausted to the outside of the plant by a fan 16 leading from a bypass pipe 18 to an air-shaft 17. During the drying or fermentation process the windows &c. in the outer shell are closed and the cooling plant is set in operation to secure a temperature of about 75‹ F. When withering has taken place, the circulation of air may be suspended and carbon dioxide, oxygen or other gas introduced through a cock on the duct 29. The process is continued until the temperature of the tobacco remains steady and the air temperature is then lowered to about 50‹ F for several hours before the chamber is opened for ventilation and removal of the tobacco.

Title: Improved method of and means for ascertaining the winding speed of yarn on spinning frames
IPC: D01H1/36
Filed: 1944-09-19
Abstract: 591,459. Measuring yarn speed in spinning frames. BRITISH BELTING & ASBESTOS, Ltd., and HALEY, G. L. Sept. 19, 1944, No. 17865. [Class 120 (iii] In ascertaining the winding speed of yarns on to a bobbin on a spinning frame, there is employed a method of measuring the speed difference between flyer and bobbin consisting in linking two equivalent rotative elements, e.g., in their respective drives, through an indicating device adapted to be controlled by the difference in revolutions and to indicate the speed difference over a given period of time. In the modification of Fig. 2, contact strips 5 are attached to the flyer and bobbin driving shafts 3, 4 respectively, the strips 5 being joined in electrical circuit by wipers 7, to a battery 9 and a lamp 10. Since the bobbin rotates one more revolution than the flyer in a given period of time, the lamp flashes occurring in a given time, with correct working, are known. Any deviation therefrom, given by the lamp 10, will indicate incorrect working and the operative will take correcting action. In the modification of Fig. 3, a spiked roller 22, driven by a gear train from the top feed roller shaft through a gear 14, makes marks 26 on a wax-coated paper tape 19 running off a spool 20. A pressure roller 21 may be applied to the tape 20 by a crank, spring and lever mechanism 27, 28, 29, so that the marks 26 will indicate, say half-inch feed per revolution of the top roller. A brass contact stud rotating with the flyer and a similar stud rotating with the bobbin are adapted to contact insulated depressable springs forming part of an electrical circuit which operates an electro-magnet 37 to move a stylus 33 to apply marks 39 to the tape 19. The distance between the centre points of two groups of markings 39 is therefore known and the number of revolutions of the' top roller is deduced therefrom. During the corresponding time, the bobbin has made one more revolution than the flyer and hence from the measured mean diameter of the lap on the bobbin, the winding speed may be computed. In a further modification, a differential gear is arranged between the flyer and bobbin shafts. The neutral gear mounting carries a pointer which in revolving indicates the difference in speed of the flyer and bobbin shafts. The revolutions of this pointer past a fixed point are either counted in a given time or used to close an electrical circuit to give lamp flashes which are counted, as in the modification of Fig. 2 above.
